will show table status display exact rows in the table?

Question

I have a table in DB and it is approx 90 GB in space. I tried to count no of rows in the table select count(idNewsNotification) from notification and it resulted <

Answer 1

This is not a good one, in some cases.

For InnoDB tables, the row count is only a rough estimate used in SQL optimization. (This is also true if the InnoDB table is partitioned.)

TEST:

I have the same db (dumped and imported on different server) both innoDB

Same table:

Server One: 49,231
Server Two: 53,242

49231 is not correct and You can see this table with "~" mark in phpmyadmin
